Which ones do you digging firsts in 22re
Hi There,
First, you will want to "snug" all the bolts down evenly. (A little more than hand tightened without compressing the head gasket)
Second, (You'll need an accurate torque wrench for the next two steps) start with the center most head bolt and work your way out to the outer most bolts in a clockwise circle and tighten the bolts to around half of the manufactures spec.
Third, tighten to full torque using the same sequence.
This sequence is a general rule of thumb for all non-specialty engines. Manufacturer's specs and recommendations shall take precedence over any advice I may give.
Good Luck!

Tip: It's always a good idea to put a light coat of oil on the head bolt threads when re-installing to prevent them from seizing.
Here is a torque spec table. Find your engine for the specs. http://olybrake.com/pdf/fel_pro_torque_specs_guide.pdf
SOURCE: tightening head
New Headbolts are recommended
Long bolts are torqued to 46'lbs + 90 degrees.
Short bolts are torqued 43'lbs + 90 degrees.
Start in the center, and work to the edges, torquing the bolts in two stages.
Rockers are torqued to 22'lbs.

You can call your local autoparts store, and they should be able to give you the proper torque.

Head bolts are torque to yeild so you MUST use new bolts.
Tighten cylinder head retaining bolts in numerical sequence in three steps as follows:
Loosen retaining bolts one at a time two to three revolutions and retighten as follows:
Long bolts:
Short Bolts:

Exhuast manifold torque 38 foot pounds, Head bolts are 38 Foot pounds after you add sealant to the bolts then after torque go another 130 degrees. Tighten center 4 bolts in sequence another 30 degrees.

Oldsmobile built engines
On the V8, tighten the bolts, in the sequence illustrated, to 100
ft. lbs. When all bolts have been tightened to this figure, begin the
tightening sequence again, and torque all bolts to 130 ft. lbs.
On V6's, tighten all head bolts in sequence to the following
torques:
* All except bolts 5, 6, 11, 12, 13 and 14 - 100 ft. lbs.(19-135.5
Nm)
* Bolts 5, 6, 11, 12, 13, and 14 - 41 ft. lbs. (19-55.5 Nm)
* All bolts except 5, 6, 11, 12, 13, and 14 - 142 ft. lbs. (19-192.5
Nm)
* Bolts 5, 6, 11, 12, 13, and 14 - 59 ft. lbs. (19-80 Nm)
Hope this help (remember comment and rated this).
